Question

1. Can a ping pong ball have greater momentum than a bowling ball?

2. Rank these cars in order of increasing momentum:

Car A: 1000 Kg moving at 20 m/s

Car B: 1200 Kg moving at 30 m/s Car C: 2000 Kg moving at 3 m/s

3. A volleyball with a momentum of .85 kg m/s has a mass of .12 kg. What is it's speed?

4. What impulse is delivered to a baseball struck with a force of 2350 N when the bat contacts the ball for .0013 s?

5. As you drive your car at 65 mph, you feel a gust of wind push the

car from the front dropping your speed to 63 mph temporarily. Is

the wind internal or external to the system?

6. Two ice skaters stand at rest in the center of an ice rink. When they push off against one another, is the force internal or external to the system?

If the 45 kg skater acquires a speed of .65 m/s what is the speed of the other skater who is 55 kg?

7. A 92 kg astronaut and a 1200 kg satellite are at rest relative to the nearby space ship. The astronaut pushes on the satellite, giving it a speed of .25 m/s away from the ship. 11.4 seconds later the astronaut reaches the ship. What was the initial distance from the ship to the astronaut?

Answer 1

Answer: A, C, and D

Momentum can be thought of as mass in motion. An object has momentum if it has its mass in motion. It matters not whether the object is of large mass or small mass, moving with constant speed or accelerating; if the object is MOVING, then it has momentum!
